Definitions
- the invention relates to an assembly according to the preamble of claim 1.
- the invention further relates to an airbag for such an airbag Assembly and a method for folding an airbag for a Airbag rope impact protection device of such an assembly.
- the invention has for its object a module of the beginning continue to develop in such a way that the said Hazard is largely avoided.
- this is associated with an assembly having the features of claim 1.
- the airbag When inflated, the airbag first unfolds towards the outside of the vehicle and then upwards. Therefore, the head of the vehicle occupant not hit from below and pushed up, but covered with the entire area and moved to the inside of the vehicle.
- the invention also provides an airbag for an airbag side impact protection device an assembly according to the invention.
- the invention also relates to a method for folding a Airbags for an airbag side impact protection device according to the invention module
- the method according to the invention is first for folding an airbag explained.
- 2 to 7 is a Airbag for a side impact protection device after each Steps of the folding method according to the invention shown.
- in the 3 to 6 and in FIG. 7 is a section seen through the gas bag after the corresponding process step.
- the airbag is initially installed with the later spread upwards towards the vehicle side wall, see above that the injection opening or the gas generator 20 mounted thereon after front (in the drawing below) and the one inflated above section 24 located to the right of the injection opening (Fig. 2).
- Section 24 is along one from the right edge of the Gas generator folded backward line 26 to the left (Fig. 3).
- Half of the top section 24 folded to the left is along a parallel to the first fold line 26 second fold line 28 folded to the right (Fig. 4).
- the after half folded on the right is divided again and the outer half Section 30 folded to the left, so that now by the three times Folded parts of the upper section 24 in one Stack one above the other (Fig. 5).
- FIG. 1a-1f shows an assembly according to the invention, that of a vehicle structure 10 with a vehicle side wall 12 and a seat 14 there.
- the seat 14 has a backrest 16.
- In the backrest 16 is on the side facing the outside of the vehicle Side an airbag side impact protection device 18 with a Gas generator 20 and a gas bag 22 installed.
- the gas bag 22 is folded according to the previously described method according to the invention.
- the gas generator 20 becomes ignited and delivers compressed gas which flows into the gas bag 22.
- the gas bag 22 initially unfolds essentially along the Vehicle side wall 12 in the direction of travel of the vehicle - in the drawings perpendicular to the image plane.
- the upper section 24 thereby forms a stack on the outside of the Airbag 22.
- the Airbag 22 continues, with the zigzag folded upper Section 24 initially essentially in the direction of the vehicle side wall 12 moves (Fig. 1b and 1c).
- the upper section 24 unfolds on the vehicle side wall 12 along upwards (Fig. 1d and 1e) until the gas bag 22 is complete is unfolded (Fig. 1f).
- the airbag folded in this way can be used Do not hit a vehicle occupant from below on the head Exercise (chin hook), even if it is not in an optimal one Sitting position or if it is about a toddler, who kneels on the seat and turns his head back or to the side.
- the invention is not limited to the embodiment shown limited. Rather, the gas bag side impact protection device with the gas bag just as well in the back of one Rear seat or in the dashboard, for example near the A-pillar installed.
- the zigzag fold of the upper section 24 is also another, for example a spiral, or other fold conceivable if they have a stack on the outside of the gas bag 22nd results, so that the upper portion first unfolds in the direction the vehicle side wall moves.
